Ukuxhumana okungenamkhawulo phakathi kwe-white corundum nobuchwepheshe besikhathi esizayo
Wonke umuntu osemkhakheni wezobuchwepheshe uyazi ukuthi izinto ezintsha ziyimali eshibhile. Ubani obengacabanga lokho?i-corundum emhlophe, ebukeka njengoshukela omhlophe, izoba “umgqugquzeli ongabonakali” wenguquko yezobuchwepheshe yesikhathi esizayo. Kusukela kuma-chips omakhalekhukhwini kuya ezingxenyeni ze-Mars rover, kusukela kumakhompyutha e-quantum kuya kumadivayisi e-fusion enuzi alawulwayo, ingatholakala yonke indawo. Namuhla, ake sisuse lolu ngqimba lobuchwepheshe bese sibona ukuthi lo mculi wezimboni wenza kanjani izinto ezinhle ngokuthula.
1. “Izakhi zofuzo zobuchwepheshe” ezinesiphiwo
Izakhiwo eziqinile ze-corundum emhlophe zenzelwe ubuchwepheshe besikhathi esizayo. Ngobunzima be-Mohs obungu-9.0, umoya mubi kakhulu kunedayimane. Ifektri yemishini ye-photolithography eShanghai yenze ucwaningo lokuqhathanisa. Ubulukhuni bomphezulu wesitimela esiqondisayo obucwebezelwe nge-corundum emhlophe bungafinyelela ku-Ra0.008μm. Uchwepheshe uXiao Li wabamba umsebenzi wokusebenza washaya izindebe zakhe: “Ngalokhu kunemba, umiyane ungaphula ithambo uma umi phezu kwawo!”
Ukuzinza kokushisa kuyamangalisa nakakhulu. Idatha evela elabhorethri yokuhlanganiswa kwe-nuclear elawulwayo eQingdao ibonise ukuthi izitsha zobumba ezimhlophe ezisekelwe ku-corundum zikwazile ukumelana nokushisa okuphezulu okungu-2000℃ amahora ayi-100, kanti ushintsho losayizi lwalungaphansi kuka-0.01%. Umcwaningi uLao Wang washaya i-vacuum chamber wathi: “Lezi zinto zingama phezu kwelanga izinsuku ezimbili!”
2. “Abaqhawe Abafihliwe” Ensimini Ye-Semiconductor
Empini yempi yokukhiqiza ama-chip ngesilinganiso esincane, i-corundum emhlophe ibilokhu “iyindela ekhukhumezayo”. Ifektri ye-wafer eTaizhou yasebenzisa i-0.1μm white corundum micro-powder ukusika ama-wafer e-silicon, futhi izinga lokuwa komngcele lehliswa laba ngu-0.2‰. UMaster Lao Chen wabuka imakroskopu wahleka: “Manje ukusika ama-wafer kusebenza kahle kakhulu kunokusika i-tofu, futhi izinga lokukhiqiza lifinyelela ngqo ku-99.98%!”
Ukupholishwa kwelensi yomshini we-lithography kuyiqiniso nakakhulu. Imininingwane evela elabhorethri eBeijing iyamangaza: ilensi iphathwa ngoketshezi olumhlophe lwe-corundum nano-polishing, kanti ububanzi bomphezulu bufinyelela ku-λ/50 wavelength. Umqondisi Wezobuchwepheshe uLao Liu wabonisa isandla wathi: “Lokhu kunemba kufana nokufaka isibuko sendiza oLwandlekazi iPacific!”
3. “Inkosi Yokucindezela” Embonini Yezindiza
I-corundum emhlophe inezwi lokugcina ekucutshungulweni kwezingxenye ze-Mars rover. Ifektri ethile yamadivayisi ezindiza e-Xi'an isebenzisa amasondo okugaya e-corundum amhlophe ukugaya ama-bracket e-titanium alloy, futhi ukucindezeleka okusele kobuso kulawulwa ngaphakathi kwe-±5MPa. Unjiniyela Omkhulu uLao Zhang uthe ephethe ugwayi emlonyeni wakhe: “Ngaleli zinga, uMusk kufanele adlulisele ugwayi ukuze acele iseluleko!”
Ama-blade enjini yezindiza asefinyelele amazinga aphezulu. Imininingwane yenkampani ethile yezinjini zezindiza eChengdu iyakhanga: ama-blade amhlophe ahlanganiswe nge-corundum ceramic, anokumelana nokushisa okufika ku-1600℃. Umshayeli wokuhlola uLao Li wabheka ideshibhodi wabe esekhala: “Ngalo msebenzi, izinjini zejethi kufanele zibize ubaba!”
4. "Isiqinisekiso Sokukhuthazela" ku-New Energy Track
I-corundum emhlophe inekhono elihle kakhulu lokusika izingcezu zezigxobo zebhethri lamandla. Ifektri yebhethri eNingde ilinganise: isebenzisa ucingo lwesihlabathi se-corundum olumhlophe ukusika izembozo ze-graphene, ukuphakama kwe-burr kulawulwa kube ngaphansi kuka-0.5μm. Umqondisi we-workshop uLao Zhou washaya iseli lebhethri wathi ngenjabulo: “Ubuningi bamandla aleli bhethri bungcono kunobukaTesla!”
5. "Ukubuka Kukabusha Kwezobuchwepheshe Obumnyama" kwe-Future Battlefield
I-White corundum inekhono elihle ekupholiseni amakhompyutha e-quantum. Ilabhorethri eHefei isungule ifilimu yokushisa ye-white corundum enesikali esincane esine-conductivity yokushisa engu-400W/m·K. Umcwaningi uLao Ma waqhosha wathi: “Manje ukushabalaliswa kokushisa kwama-quantum bits kushesha kunokusebenzisa i-fever patch!”
Izinto zokuqala zodonga lwe-nuclear fusion zinamandla aqinile kakhulu. I-white corundum composite ceramic yesikhungo socwaningo eMianyang inomkhawulo womonakalo we-neutron irradiation ophakeme ngokuphindwe kasithupha kunowezinto zendabuko. Unjiniyela Omkhulu uLao Zhao wakhomba i-reactor wathi: “Lezi zinto zizohlala zizinzile kuze kube yilapho i-reactor yezentengiselwano ifakwa ekukhiqizweni!”
